For example, there are 10 jigs on the transmission line, and there are 20 sealing plates 21 corresponding to the 10 jigs (one sealing plate is located at the front side and the rear side of the jig), and the distances between two adjacent sealing plates 21 are L1 respectively₁、L1₂、 L1₃、L1、L1₅、L1₆、L1₇、L1₈、L1₉、L1₁₀Then L1_maxIs (L1)₁、L1₂、L1₃、L1、L1₅、L1₆、L1₇、L1₈、L1₉、L1₁₀) Of (e.g. L1)₃At the maximum, L1_max＝L1₃(ii) a Correspondingly, since the 10 jigs are sequentially arranged in a ring shape, or the ring shape is opened to be arranged in a linear shape, for convenience of description and illustration, the jig is described as being arranged in a linear shape. The lengths of the four sliding channels in this embodiment are respectively L0₁、L0₂、L0₃L0, then L0_minIs (L0)₁、L0₂、L0₃L0), e.g. L0, L0_minL0, L0 ≧ L1₃。

When there is a tool continuously entering into the initial entering end of any container, several tools continuously move forward and horizontally with the sealing plate 21, due to L1_iAnd L0_iThe following conditions (not limited to the following conditions) exist in each slide channel, and the following takes the case that the length of each slide channel is equal and the distance between any two adjacent sealing plates 21 is equal as an example.

In the first state: when L0_min＝L1_maxIn the case of two adjacent jigs, as shown in FIG. 6a, the result is L0_min＝L1_maxThe rear side sealing plate 21 of the front jig and the sealing plate 21 of the rear jig at the front end are respectively just plugged on the outlet end and the inlet end of a sliding channel, and two ports of the sliding channel are sealed, so that the inner cavity of the sliding channel is separated from the inner cavity of the container where the sliding channel is located; if the sealing plate 21 continues to move forward, as shown in fig. 6b, the front end sealing plate 212 of the rear jig enters the sliding channel to slide hermetically, so as to seal the sealing channel, and if the front end sealing plate 21 of the rear jig continues to move forward, as shown in fig. 6c, the front end sealing plate 21 of the rear jig just moves to the outlet of the sliding channel, at this time, the upper sealing plate 21 at the rear end of the jig just blocks at the inlet of the sliding channel, so that at least one sealing plate 21 is arranged in each sliding channel, or one sealing plate 21 is respectively blocked at the inlet and the outlet of the sliding channel, so as to seal the sealing channel 33, and similarly, one sealing channel is sealed.

In the second state: when L0_min＞L1_maxIn the two adjacent jigs, as shown in fig. 6d, the sealing plate 21 on the rear end of the front jig and the sealing plate 21 on the front end of the rear jig are both positioned in the same sliding channel to slide in a sealing manner, and two sliding sealing partition walls are formed in the sliding channel; if the sealing plate 21 continues to move forwards, after the front jig is moved out of the sliding channel, the sealing plate 21 at the front end of the rear jig slides in the sliding channel in a sealing manner, and if the rear jig continues to move forwards, a sealing and isolating effect is achieved between the sliding channel and the inner cavity of the container. Or as shown in fig. 6e, the front end sealing plate 21 of the jig just moves out of the sliding channel, and at least part of the rear end sealing plate 21 of the jig enters the sliding channel for sealing and sliding.

Therefore, at least one sealing plate 21 in each sliding channel slides in the sliding channel in a sealing manner, or the inlet and the outlet of each sliding channel are respectively sealed and blocked by one sealing plate 21, so that the inner cavity of each sliding channel is sealed and separated from the inner cavity of the container in which the sliding channel is positioned, and the solution in the container is prevented from continuously entering the sliding channel; only in two adjacent jigs, there is a small amount of solution in the clearance between the closing plate 21 of the rear end of the preceding jig and the closing plate 21 of the front end of the rear jig, and there is a small amount of solution in the gap between two closing plates 21 at the same jig both ends, outside being taken out the channel that slides, thereby make the range of the liquid level height reduction of solution in this container little, and then only need to move closing plate 21 along the horizontal direction and just can drive the jig to remove in succession, the solution in two adjacent containers also can not mix, with the jig from a container transfer to another container in, carry out the processing of different processes to the work piece in the jig in succession, simplify the work piece course of treatment and be convenient for follow-up batch processing work piece.

As shown in fig. 7, the processing apparatus 3 includes, in addition to two second containers 31 and the electrochemical processing assembly 32: a reservoir 34 and a liquid level circulating mechanism. As shown in fig. 8, 9 and 10, the reservoir 34 is disposed corresponding to the sealing channel 33 for receiving the processing liquid flowing out from the opening of the sealing channel 33. The reservoir 34 is arranged in communication with the second container 31 via a level circulation mechanism which ensures that the level of the liquid in the second container 31 remains constant. For example, in the present embodiment, the processing device 3 has two reservoirs 34 disposed in communication with each other, and the reservoirs are in communication with each other through a communication pipe. The liquid level circulating mechanism comprises a circulating pump 35 and an overflow channel 36; the circulation pump 35 replenishes the flow of the treatment liquid in the reservoir 34 into the second container 31; both ends of the overflow passage 36 are respectively provided in communication with the second container 31 and the reservoir 34. By providing the circulation mechanism, the solution flowing out of the second container 31 is collected and transferred into the second container 31 again on the side of the sealed passage 33 communicating the second container 31 and the post-treatment device 4 with each other, so that the liquid level in the second container 31 is ensured not to be lowered, and the consistency of the solution in the second container 31 and the liquid level stability of the solution volume are ensured.

As shown in fig. 11, in the present embodiment, each of the pretreatment apparatus and the post-treatment apparatus has a rinsing mechanism for cleaning the workpiece, and the rinsing mechanism includes: a pickling treatment chamber 421 and a liquid spraying unit. Specifically, the liquid ejecting unit is provided on an inner wall surface of the immersion cleaning processing chamber 421; and spraying the immersion liquid to the workpiece side. In this embodiment, the spray unit has a first liquid outlet 423 disposed on one side wall of the immersion processing chamber 421, and a second liquid outlet 424 on the opposite other side wall of the immersion processing chamber 421. The liquid outlet flow of the first liquid outlet 423 is larger than the liquid outlet flow of the placing cavity of the jig 2 for accommodating the workpiece, and the liquid outlet flow of the second liquid outlet 424 can be smaller than the liquid outlet flow of the first liquid outlet 423. For example, when the immersion reaction is performed on a workpiece placed in the cavity, the opening side of the placing cavity for accommodating the workpiece of the jig 2 faces the first liquid outlet 423, the treatment liquid flowing out of the first liquid outlet 423 can enter the placing cavity for accommodating the workpiece of the jig 2, and since the liquid discharge flow of the placing cavity is smaller than the liquid discharge flow of the first liquid outlet 423, a certain water level can be formed in the placing cavity, so that the immersion reaction is performed on the workpiece. The second liquid outlet 424 is used for cleaning the back surface of the fixture 27 during cleaning, so that the flow rate of the required flushing liquid is small, the liquid outlet flow rate can be reduced, the power output of the liquid flow output end of the liquid spraying unit can be saved, and the energy can be saved. For example, the fluid output may be a delivery pump 422.

A liquid outlet channel 425 vertically arranged is arranged on the side wall of the immersion cleaning treatment cavity 421, one end of the liquid outlet channel 425 is communicated with a liquid outlet, and the other end of the liquid outlet channel 425 is used for being communicated with an outlet of the conveying pump 422; the liquid outlet channel 425 is arranged on the side wall, so that the arrangement of pipelines can be reduced, and the whole equipment is simpler; because the liquid flowing out of the liquid jet unit has larger liquid outlet flow, the liquid can flow out towards the workpiece in the form of a water curtain, so the liquid outlet pressure of the liquid is smaller, and when the liquid impacts towards a jig or a workpiece, a large impact force cannot be generated, thereby preventing a large amount of liquid from splashing outside the immersion cleaning treatment cavity; due to the vertical arrangement, the liquid discharge pressure of the conveying pump 422 can be reduced, so that the liquid flows out from the liquid outlet at a large flow rate and a small pressure, and the liquid flowing out from the liquid outlet can be further made to present a water curtain form. Also, as an alternative embodiment, the outlet channel 425 may not be provided in the side wall, for example a conventional liquid supply hose may be used instead.

As shown in fig. 12, the post-processing apparatus further includes an air drying mechanism for blowing air to the jig 2. Air-dry mechanism includes: air-dry processing chamber and gas injection unit. Wherein, the gas injection unit is arranged on the inner wall surface of the air drying processing cavity; for jetting an air flow towards the jig 2.

The present embodiment provides a specific implementation manner of a workpiece drying device, as shown in fig. 12, including: air-dry processing chamber and gas injection unit. The gas injection unit has a source 434 of hot air that is blown into the air-drying chamber. The gas injection unit includes a blowing port, a blowing passage 433, and a wind source 434.

As shown in fig. 12, the seasoning chamber has two opposing sidewalls. When the jig 2 passes through, the air blowing ports on the two side walls blow the workpiece carried in the jig 2 and the jig 2 together through blowing hot air to remove the residual post-treatment liquid on the workpiece and the jig 2 carrying the workpiece.

Specifically, the air blowing port has a first air blowing port 431 and a second air blowing port 432, and the first air blowing port 431 and the second air blowing port 432 are provided on two opposing side wall surfaces in the seasoning processing tank, respectively. When the first air blowing opening 431 is accommodated in the air drying channel at the workpiece and the jig 2 bearing the workpiece, the nozzle of the first air blowing opening 431 is ejected towards the opening side of the jig 2 placing cavity, and the blowing flow of the second air blowing opening 432 is smaller than the blowing flow of the first air blowing opening 431. That is, the first blowing opening 431 is used for blowing the workpiece accommodated in the jig 2 and the front surface of the jig 2, so that the blowing amount is set to be large, and the blowing effect can be ensured; the second air blowing port 432 is used for blowing the back of the jig 2, and the air blowing amount is small, so that the air blowing amount can be properly reduced, the power output of the air source 434 can be saved, and the energy can be saved. In addition, as an alternative embodiment, the blowing flow rate of the second blowing port 432 may not be reduced, and the blowing flow rates of the blowing ports may communicate with each other by the size of the opening of the blowing port.

Be provided with on the lateral wall of air-drying treatment chamber and blow passageway 433, blow the mouth of blowing of one end intercommunication of passageway 433, the other end is used for with wind regime 434 intercommunication. With blowing passageway 433 setting on the lateral wall, reducible pipeline arrange, make equipment whole succinct more. In addition, as an alternative embodiment, the blowing channel 433 may not be provided on the side wall, and for example, a conventional air supply hose may be used instead. Because the jig is a barrel plating barrel, and one side of a placing cavity of the barrel plating barrel, which is used for accommodating the workpiece, is of an opening structure, the air blowing port on one side of the workpiece drying device can blow air directly towards the workpiece through the opening structure of the placing cavity; in addition, in the process of blowing air towards the workpiece through the air blowing port, the workpiece can be rolled through the barrel plating barrel, so that the workpiece can be rolled and blown at the same time, and the air drying efficiency of the workpiece is improved. The bottom of the barrel plating barrel is provided with a plurality of uniformly arranged liquid discharge holes, and the reaction liquid in the placing cavity and the reaction liquid flowing out of the workpiece through rolling can flow out to the lower part through the liquid discharge holes. The air-drying treatment cavity is communicated with a post-treatment liquid storage cavity, and liquid flowing out of the barrel plating barrel in post-treatment can enter the post-treatment liquid storage cavity for recycling. The bottom of the post-treatment liquid storage cavity is provided with an inlet of the pump body, and post-treatment liquid can be recovered into a container of the previous process by driving the pump body, so that the consumption of the post-treatment liquid is reduced.

The workpiece processing production system in the present embodiment, as shown in fig. 1, 7 and 9, further includes an exhaust device 5. The exhaust device 5 is communicated with the pretreatment device, the workpiece treatment device and the post-treatment device 4 to exhaust the escaping gas.

A vent 51 formed in either of the container sidewalls; the negative pressure source communicates with the exhaust port 51. Specifically, the negative pressure source is a negative pressure generator, and the negative pressure generator is connected to the exhaust port 51 through a pipe. The exhaust channel is a transverse pipeline arranged in the middle of the annular production line and a longitudinal pipeline which is respectively communicated with the inner rear side wall surfaces of all containers; the height of the vent 51 in the second container 31 is higher than the height of the overflow port 37, and since evaporation often occurs at the interface between the liquid and the gas, the vent 51 higher than the height of the overflow port 37 ensures a concentrated treatment of the escaping gas.

In the workpiece processing and producing system provided by this embodiment, the workpieces are sequentially driven along the pre-processing device, the processing channel and the post-processing device 4, and the two ends of the second container 31 on the processing device 3 are provided with the sealing channels 33, so that the sealing channel 33 is connected with two adjacent containers in a sealing way, so that at least one workpiece in each workpiece sealing channel 33 slides in the sealing channel 33 in a sealing way, and the solution between two adjacent containers is ensured not to be mixed with each other, and only in the adjacent two works, a small amount of the solution existing in the gap between the rear end side of the front work and the front side of the rear work is carried out of the sealed passage 33, so that the reduction of the level of the solution in the container behind the sealed passage 33 in the transport direction is small, thereby realizing that the liquid level is reduced very little and the solutions in two adjacent containers can not be mixed; meanwhile, the workpieces are transferred from one container to another container, and the workpieces are continuously subjected to procedures such as pretreatment, processing treatment, post-treatment and the like, so that the workpiece treatment process is simplified, and the subsequent batch treatment of the workpieces is facilitated.

The channel body 331 comprises two opposite channel side walls, and the jig 2 is allowed to pass between the channel side walls; and a wiper seal assembly provided on the side wall of the passage, the wiper seal assembly including a plurality of wiper seals 3321 provided along the traveling direction of the pretreatment workpiece, the seal member entering the passage body 331 and being sealingly and slidably connected with the wiper seals 3321. Of course, the channel body may also be provided with three sets of wiper seals 3321, on the two side walls and the bottom wall, respectively.

The wiper seal assembly in this embodiment includes a plurality of wiper seals 3321 and sets of seal mounts. The wiper seal 3321 is disposed along the conveying direction of the jig 2, and detachably disposed on the inner wall surface of the passage body 331 through a seal fixing member.

In the moving process of the jig 2, the end part of the scraping blade sealing piece 3321 is just abutted against the sealing plate 21; or if the length of the blade seal 3321 is long, the blade seal 3321 is bent by the sealing plate 21, and a part of the side portion of the blade seal 3321 is attached to the sealing plate 21, that is, the blade seal 3321 has a bending length attached to the sealing plate 21 when bent by the sealing plate 21, at this time, it is required to satisfy that the bending length of the bent blade seal 3321 is less than or equal to the distance between adjacent blade seals 3321, so as to ensure smooth movement of the jig 2.

In the above-mentioned sealed channel, since the length of the sliding channel in embodiment 1 is the actual acting sealed length between the sealing roller and the jig in this embodiment, the actual length of the sliding channel is the same as that of the channel body.

Example 3

This embodiment provides a workpiece processing production system which is different from the workpiece processing production system provided in embodiment 1 or embodiment 2 in that: the sealing channel 33 is structurally different:

Of course, as shown in fig. 16, three sets of sealing rollers may be provided on the channel body, respectively on the two side walls and the bottom wall surface.

In this embodiment, the roller assembly includes a first transmission member 3332, a second transmission member 3334, a rotation shaft 3333, a driving member, and a plurality of seal rollers 3331. The first transmission piece 3332 and the second transmission piece 3334 are arranged in a transmission manner, the first transmission piece 3332 is sleeved on the outer side of the rotating shaft 3333, the second transmission piece 3334 is arranged at the top of the sealing roller 3331, and the rotating shaft 3333 and the driving piece are fixedly connected with each other. Specifically, the driving member is a rotating motor; the sealing roller 3331 is an elastic roller and is made of a sponge roller sleeved outside the rotating shaft 3335, and in other optional embodiments, materials with elasticity such as rubber materials can be selected, so long as the jig 2 can rebound and reset under the action of the elastic roller after extruding the sealing roller 3331; the first transmission member 3332 and the second transmission member 3334 are gears engaged with each other. When the rotating motor rotates, the first transmission piece 3332 and the second transmission piece 3334 are sequentially driven to rotate, and the seal roller 3331 is driven to rotate.

In the process of processing the workpiece, the sealing plate 21 is connected with the outer peripheral surface of the elastic sealing roller 3331 in a rolling manner in a sealing manner, wherein the workpiece to be processed is carried by the jig 2 to move in the channel body 331, specifically, the jig 2 moves in the channel body 331 under the driving of a driving mechanism on the processing equipment, the rotating direction of the sealing roller 3331 is the same as the moving direction of the workpiece, the elastic sealing roller 3331 provides forward compensation force for the sealing roller 3331 under the driving of the driving piece, and the forward compensation force and the forward driving force of the driving jig 2 act together, so that the jig 2 carrying the workpiece can be processed and output efficiently and stably. In the above-mentioned sealing channel, since the length of the sliding channel in embodiment 1 is the actual acting sealing length between the sealing roller and the jig in this embodiment, the sliding channel is the difference between the length of the channel body and the diameter of one sealing roller.

Example 4

This embodiment provides a workpiece handling production system which is different from the workpiece handling production system provided in any one of embodiments 1 to 3 in that: the sealing channel 33 is structurally different:

as shown in fig. 19, the seal passage 33 includes: the channel body 331 and the synchronous belt component, wherein the channel body 331 allows the pretreatment workpiece to pass through; the synchronous belt component is arranged in the channel body 331 and can circularly move in a closed ring; a sliding channel for sliding the workpieces is formed between the inner side wall of the synchronous belt assembly and the inner wall of one side opposite to the second container 31, and at least part of the other side walls of the synchronous belt assembly is in sliding abutment with the inner wall of the other side of the second container 31; the inner wall of the slide channel is sealably slidably connected to the seal member. Of course, three groups of synchronous belt assemblies can be arranged on the channel body and are respectively arranged on the two side walls and the wall surface at the bottom, and the purpose of realizing the sealing and sliding of the jig in the sealed channel can be further met.

For example, the timing belt assembly has a timing belt body 3341 rotatably provided in the conveying direction, and the timing belt body 341 is rotatably provided below the driving wheel 3342. In the above-mentioned sealing channel, since the length of the sliding channel is the actual acting sealing length between the timing belt body 3341 and the jig in the horizontal direction in this embodiment, the sliding channel is the difference between the length of the channel body and the diameter of one driving wheel 3342 in this embodiment. The jig 2 can also slide in the sliding channel in a sealing manner. When a plurality of jigs continuously slide and pass through the sliding channel along the conveying direction, the inner wall of the sliding channel can slide on the outer wall surface of the sealing component in a sealing manner, so that the sliding channel is sealed in a sliding manner under the matching of the inner side wall of the synchronous belt component and the workpiece, and the outflow quantity of the solution from the inside of the sliding channel to the outside is reduced; because the synchronous belt component moves circularly, the sliding butt is formed between the inner side wall of the synchronous belt component and the outer wall surface of the sealing component, the friction force between the contact surfaces of the synchronous belt component and the sealing component is reduced, and the service life of a sealing surface formed by the contact surfaces of the synchronous belt component and the sealing component is long;

meanwhile, the outer side wall of the synchronous belt component is respectively abutted to the inner wall of the other side of the sealing channel 33 in a clearance fit or sliding manner, so that a small clearance or clearance-free fit exists between the outer side wall of the synchronous belt component and the inner wall of the sealing channel 33, and the solution in the first area between the outer side wall of the synchronous belt component and the inner wall of the sealing channel 33 can be blocked, therefore, under the cooperation of the synchronous belt component and the workpiece, most of the solution in the sealing channel 33 is blocked in the inner cavity of the container, the outward outflow of the solution in the container through the inlet end or the inlet end of the sealing channel 33 is reduced, the speed of the liquid level reduction of the solution in the container is slowed, and the influence on the subsequent batch processing of the workpiece.
